Rock Drill Tools

Threaded Rock Drilling Bits

Threaded bit by bit pants body thread and thread drill rod connected to achieve percussive and rotary transmission, a kind of drill rock broken out. The use of advanced gear forming technology and optimized product design, mainly used for roadway driving, underground, open pit mining, tunnel and large - scale construction projects.

Dth Hammer Bits

DTH bits (also called DTH bits or spline connection bit) is connected through the drill bit spline and impactor, for impact orientation and rotation of a transmission, braze the broken rock. Mainly used in large mines (open pit and underground mining), open architecture, and a large stone mining engineering construction conditions.

Cutters For Hard Rocks

Underground mining tools include Hob, steel tool ring, insert tool ring and so on, suitable for UNIAXIAL compressive strength of more than 40 MPA of hard rock, ultra-hard rock and so on. JLDQ001, JLDQ002 and JLDQ003 steel tool rings have been developed in collaboration with Central South University and University of Science and Technology Beijing. Through advanced vacuum heat treatment process and gradient heat treatment process, the tool ring is suitable for hard rock, super-hard rock strata and soft-hard composite strata with rock strength between 40MPA and 240MPA, and the wing-shaped tooth insert tool ring and block insert tool ring are developed for composite strata below moderate weathering, it can ensure long-distance driving without changing cutter and improve construction efficiency.

Coal Mining Picks

Coal cutter Luoyang gol- egret production including shearer pick (durable), roadheader pick (Ying Yan type) and no spark series (assault type), the product production process using the most advanced, the most high-quality raw materials, has good abrasion resistance, impact toughness, long service life and the work efficiency is high.
